We look at the division of 311433 by 78 
We want to divide 311433 by 78.

Let's proceed to step 1:
78 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 78

Going ahead to step 2:
78 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 78

Advancing to step 3:
311 divided by 78 is 3 with a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 234 from 311 leaves us with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 78

Advancing to step 4:
The number 78 fits into 774 9 times, leaving a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 702 from 774 to get 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 78

Going ahead to step 5:
If we divide 723 by 78, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 399.0
The remainder is 21 after subtracting 702 from 723.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 78

Going ahead to step 6:
78 can be fit into 213 2 times, resulting in a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 3992.0
If we subtract 156 from 213, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
78 goes into 570 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 3992.7
If we subtract 546 from 570, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
78 goes into 240 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3992.73
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
60 divided by 78 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 3992.73
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
78 can be fit into 600 7 times, resulting in a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 3992.7307
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 3992.73076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 3992.730769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
If we divide 180 by 78, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3992.7307692
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
78 can be fit into 240 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 3992.73076923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 3992.73076923 with a remainder of 6e-09.
